The House of Diffusion, designed by FORM/Kouichi Kimura Architects, is a residence in Shiga, Japan. It is a striking, white composition that uses intersecting square volumes as its primary design element. The House of Diffusion is the complement to the architects’ House of Inclusion which shields its inhabitants from the exterior and is focused on an interior courtyard. The House of Diffusion foregoes an interior courtyard in favor of carefully censored views of its surroundings. Windows are placed specifically to afford inhabitants views of the landscape, but block views of the immediate neighborhood. The house’s name is also a result of its interior arrangement which uses flexible interior spaces which are “neither single nor too much divided.” Rooms are able to change definition and overlap one another.
